  1. Run II Upgrade DØ special Collaboration meeting Fermilab June 10, 2014 H.Weerts Argonne National Laboratory Anec: Boaz

  2. Introduction Not given DØ talk for ~10 years, except D0 France Used to give at least one/week There is live after DØ, but how much……. Remarkable occasion: RelearnØ This really has little to do with science, it is simply history. (except how things are accomplished) Amazing how much I forgot…….. Amazing that some things came back and I remembered them.

  3. Talk outline and plan • Run IIA upgrade activities 1996/7-2001 Try to be objective, but it is a personal view Try to do it in a historical order During 1990’s collaboration also transformed itself, grew and became more international  J.Womersley talk

  4. Lehman review March 1997 Upgrade First Lehman review I was involved in as spokes Introduction talk at our baseline review. Why me ?

  5. Lehman review March 1997 Upgrade Run I

  6. Lehman review March 1997 Upgrade Run I Run IIa Upgrades: • Momentum measurement • Vertex tagging • Better muon system • Trigger capabilities • Electronics for crossing time ; 2.4msec-> 396 nsec -> 132nsec • Shielding

  7. Lehman review March 1997 Upgrade; what was it?

  8. Upgrade Lehman review March 1997 Not part of Upgrade, but large effort: Upgrade of offline computing with changes to hardware, object oriented approach & first non-FNAL farms Later talk

  9. Lehman review March 1997 Upgrade Request base-lining of project. Upgrade Project was base-lined i.e. construction funds available and start construction in a Jan 1998 review Estimated time: Ready to roll in: Rolled & hooked up: 01 Oct 1999 29 Nov 1999

  10. The Upgrade management Mike Tuts Jim Christenson Hard to find pictures

  11. Lehman review March 1997 Upgrade cost Concerns at Lehman review March 1997. Total capital cost: $60,659K in FY95$ Need to be specific a la Tuts (upgrade $39M + Solenoid, Project support, G&A: $21M) Special Slide by J.Christenson HM & HW charged to find missing funds Have identified $1.8M Exploring other sources……. • DoE funding $3M short • Meeting Collider Schedule requires funding earlier then available from DoE • Have secured funds needed for this , but concerned about future years ? Collaborating Institutions have pledged ~$1.9M prefunding for FY97; additional $1M for FY98 Does not work

  12. D0 workshop 1997, Indiana Univ. Let pictures speak for themselves (Only picture of JC I could find) A lot of activities at Fermilab, universities and institutions worldwide; R&D ongoing; fabrication & production lines ramping up No idea what we were in for………..

  13. ~April 1999 Upgrade (~ 1.5 years after baseline) Good progress after March 1997 review for 1998…….. Concerns about how upgrade was progressing from DoE and others. Rollin date had been moved to May 2000, considered not realistic Jim Christenson resigned as Upgrade Project Manager (April 1999) Great upheaval in upgrade project and in collaboration. Reorganization of upgrade and experiment with wide impacts Many changes in next few months. DoE review coming up in June ‘99. New director coming at Fermilab. Spokes Upgrade Management Changes at top H.Montgomery H.Weerts M.Tuts H.Weerts (replace JC) Not optimal……… Scrambled through May  August 1999

  14. ~Sept 1999 Final Schedule for Run II Sept-14-99 D0 collab mtg New director (Witherell) Slipped by 6 months Realistic…. In the end accomplished this

  15. Memorable things & pictures SMT Eric Kajfasz (Marseille), Expertise limited in D0, when started…. Delays at Micron Semiconductor dictated schedule Fermilab “took” over Micron Large effort at SiDet facility D0 developed & trained a new set of Si experts  now working on new projects Install north

  16. Memorable things & pictures Fiber tracker Fiber ribbon mounting Critical: Cylinders Make ribbons of fibers Install fibers Measure fibers VLPC VLPC cryostats Fibers landing Signals out Fiber routing nightmare CFT installation in solenoid

  17. Memorable things & pictures Muon system Muon truss at Lab E “ A Russian Affair” Replaced complete forward system Trigger scintillators Min Drift tubes New trigger Muon C layer Just HUGE Best muon system (trigger) ever built

  18. Memorable things Triggers One area of close collaboration with CDF ( and MSU and U of Mich.) Develop Alpha processors (Windows NT based) One problem after the other ( more like disasters) Prototype worked, but no production…… many man years gone Started run…… replaced afterwards L2 Struggle for all involved Initially based on custom system for D0 Based on special expertise and Windows NT and custom hardware from Run I (VRBs) Delays kept on occurring. Jan 2001:it would not work Implemented new solution based on standard data transfer and Linux processors L3 Old and new groups worked together and realized a working systems within months.

  19. Installation schemes…. Called “Tutti- Frutti” Land……used to plan

  20. Dzero moved in January 2001

  21. Dzero in and its people February 2001

  22. Intertwining of DØ and HW life Complete overlap of MSU & DØ Get PhD 1981 1985 1989 1995 1999 2003 2007 2011 2014 Data DØ HW in DØ HW at MSU Anec: Nearly did not get tenure at MSU because of DØ

  23. Summary Was good to go through history ( relive some) DØ was large part of my life Reminded me that I am getting old…. Preparing this talk ( technology has moved/is moving on) It was good to see something like the upgrade come together and be an integral part of it. Great to see DØ grow (in people & in science) and be part of that as well It has been a privilege and great scientific & social experience to work on DØ and with colleagues from all over the globe. While doing it………… Looking back………….. it was a struggle and challenging it was simply a blast

  24. Summary Was good to go through history ( relive some) DØ was large part of my life Reminded me that I am getting old…. Thanks to all of my DØ colleagues Preparing this talk ( technology has moved/is moving on) It was good to see something like the upgrade come together and be an integral part of it. Great to see DØ grow (in people & in science) and be part of that as well It has been a privilege and great scientific & social experience to work on DØ and with colleagues from all over the globe. While doing it………… Looking back………….. it was a struggle and challenging it was simply a blast

  25. The End

  26. Lehman review March 1997 Upgrade ? D0 more international ‘84  ‘97

  27. Lehman review March 1997 Upgrade One institution from France so far….

  28. History In 1995 was on Fermilab PAC. Lots of discussion about future…. Listened and made my own extrapolation Still very optimistic numbers for Tevatronlumi for Run II andIII/TeV33 ( did not happen)

  29. DØ
